It just might work!!!!!!!!
Hey guys I just put the hammer to my lamp! It just might work. the bulb inside looks to me like one of the double ended bulbs we see everywhere. They just stick it in the long way caulk it with some kind of ceramic stuff and built a custom case for it. So if im right we can find a bulb with the right specs and just replace the bulb when it goes out in the future for about what those double ended bulbs cost now.
How long are those hqi double ended bulbs???

150w is 3.5 inches with out the end holders, and the 250w is 4.5 inche with out the end holders. which add about an inch or 2. The 150 is the most practical because its smaller, (70 even smaller but not sure if it would be bright enough). 150 also has the closest initial lumens (commercial about 10000, 150w hqi about 11000).
But you probably can't use the same ballast as your commercial projector...And the commercial projector might not like switching on with a foreign bulb in it.
So basically what i'm thinking is that it would be great to use one of these expensively designed reflectors with an HQI...but we would probably have to build a custom projector around it and find a small LCD screen to use with it.
Oh wait, sorry...forgot about the condensor lens (I think Plano-Concave lens is the best for spreading the light onto the LCD in this case)...Ok, so Small LCD is not that important. But custom projector might be needed unless you want to plug in your ballast seperately and possibly find some way to fool your commercial projector into thinking it's got the proper bulb in place.

Well the ballast in it is bigger than a 150w icecap hqi, so if i could rip out the old one i will put the new one in its place. And i took the lamp out and put the cover back on then turned it on and i heard the fan, so im assuming it turns on if the cover is screwed back on, whether or not it has a lamp in. I will try to hard wire the new ballast directly to the power port so it turns on when the switch it flipped, unless that will drain to much from the actuall projector, i really dont know anything about it.
This may not be the right place to ask,
but I have not seen this question anywhere else.
What about using one of those hunting splotlights?
I have seen some with a million candela which seems
like it could be a lot of lumens.
Thoughts anyone?

Please search the forum before you post, this subject has been discussed very much already.
Using a HQI-lamp in the way a commercial unit do is nothing new, I have already wrote very much about it starting here http://www.diyaudio.com/forums/showthread.php?s=&threadid=4240&perpage=15&pagenumber=116
Forget the UHP-reflector it´s to small to work with a HQI-lamp ! If you find a HQI-lamp with a arc-size of 1mm then it will work.

Thats just it. You hit the nail on the head there. My ENH bulb kicks butt for that reason. Longer arc but dont matter anyhow. Its brighter then my 175watt MH no kidding. Cause the tech in reflector! Most ALL light is off reflector. Thats called the clean light. Its controled-cooled and etc. The dirty light is off front not in beam, and not filtered. THats the bad light at tip. Most bulbs fog tip for that reason. ENH being one of them at times. The filiment is long ways as the light will be parallel at a 45o incidence to reflector. BUT theres more.....hehe. The reflector is dichrotic. Meaning multi-color. It filters out IR and UV when struck allowing IR heat to escape (and bad light for eyes-UV). Now your light beam is only 65% relevent brightness. ENH ansi spec says (cant believe it but its true) 15,000 lumens. Its TUNGSTEN Halogen not just halo. Filiment glows hotter lasts longer so brighter also more CRI correct. The spec will say "With 65% relative brightness". That means filiment produces 15k lumen BUT due to reflector coating the refelteced clean light resembles 65% of that brightness. Meaning 9,750 lumens in the beam of light thrown forward with lots of heat gone aswell. The rest lost in ehat and due to filter being 90% efficient. $10 bulb, 175 hours high output, 300hours energy saver mode. 😀
